Hi Martin,

I think you misunderstood what Greg was trying to convey with the above-
mentioned message.

Well, he doesn't like to feed developers with little spoons :-)

I'm pretty sure that, by "Why not use the proper debugging calls instead of 
just deleting them?", he meant you should research, understand, and use the 
proper APIs for printing debug messages.

Please check out pr_debug(), dev_dbg(), netdev_dbg(). Use them appropriately, 
according to the subsystem you're working in and to the different types of 
arguments they take.

Thanks,

Fabio
